SEAM FOR SEWED ARTICLES.

SPECIFICATION forming part of Letters Patent N o. 583,401, dated May 25,1897.

Application filed January 21, 1892, Serial No. 418,757. (No model.)

To @ZZ whom t may. concern,.-

Be it known that I, LORENZ MUTHER, a citizen of the United States,residing at Oak Park, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Scams, of which thefollowing is a description, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon.

My invention relates to an improved seam for use in uniting the edges ofknit fabrics or for ornamenting the same, the two pieces of fabric to beunited being superposed edge upon edge, stitches being passed through inthe particular manner mentioned, after which the edges of the fabric aretrimmed, the pieces spread out so as to lie in the same plane, and thenrubbed down. By the use of my particular seam and the disposition of thethreads therein each Wale of the goods is caught by the thread, thusmaking a stronger seam.

The invention consists in the combination, with the fabric, of thethreads arranged upon opposite sides of the central line of the seam, acontinuous row of loops in each thread passing down through thematerial, the loops in one row being set oblique to the correspondingloops in the other row, and an under thread having a series of loops,each passin g diagonally across the line of the seam, the loops of saidunder thread lying within two loops and inclosing two succeeding loops.

My invention is illustrated in the accompanying drawings, in whichnFigure l is a top plan view of my seam. Fig. 2 is a side elevation inperspective of the same. Fig. 3 is aplan View representing the fabricsas spread out to lie in the same plane.

In the drawings, A represents the pieces of fabric to be united, shownwith their edges superposed. The threads a h are arranged within theedge of the fabric parallel to each other and on opposite sides of thecentral line of the seam. The thread a is placed adjacent to the edgeand is provided with a continuous row of loops c, passed down throughthe fabric and secured on the under side. The thread b is arranged ata'greater distance from the edge than the thread ct and is provided witha corresponding row of loops CZ, also passed down through the materialand secured on the under side. The respective loops c cl are notarranged directly opposite, but diagonally to each other across the lineof the seam, so that the loops c come opposite the central part of thatportion of the thread h between any two loops d, the longitudinaldistance between each loop c and the next loop d of the other row beingnot substantially greater than the gage of the fabric, and by thisarrangement a stitch is practically formed in every Wale of the goods,the loops in the threads d passing through every alternate wale on oneside of central line of the seam and the loops in the threads b on theoppoe site side of the central line of the seam passing through thewales skipped by the loops in the threads a.

The loops c d Aare secured on the under side of the fabric by a thirdthread e, and it will be seen, by starting at the left Aof Fig. 2, thatthe thread e. passes first through a pair of loops d c, then around asecond pair of loops ed, then back through the first pair,-then forwardthrough the second pair and around a third pair, then back through thesecond pair and forward through the third pair, around a fourth pair,back through the third pair, and so on. The thread e therefore passestwice through each pair of loops c CZ and has a course at an angle tothe line ofthe seamin order 1o pass through the obliquely-set loops cCZ. In practice after the edges have been superposed and the seam abovedescribed applied thereto I preferably trim the edges of the fabric upclose to the thread a, then unfold the pieces of fabric, spread them outso that they lie in the same plane, and finally rub down the seam andHatten it out.

I-Iaving thus described my invention, what I claim as new, aud desire tosec ure by Letters Patent, is

In combination withl the fabric A, the

threads a b arranged upon opposite sides of the central line of theseam, a continuous row of loops in eaoll thread passing down through thematerial, the loops in one row being set oblique to the corresponding`loops in the other row7 and a thread as e, having a series of loops eachpassing diagonally across the line of the seam, the loops of said threade lying within two loops c d and inclosing two succeeding loops;substantially as described. Io

In testimony whereof I afiix my signature in presence of tWo Witnesses.
